ORDNANCE POWDER- -BAGQ $PZJGIFIGATION formingpart of Letters Patent No. 70 7,401, dated August 19, 1902. Application filed March 31, 1902. Serial No. 100,859. '(No specimens.)

To all whom it may concern.-

Be it known that I, CARL THEODOR DdRR, doctor of philosophy, residing at Ohligs, Rhenish Prussia, Germany, have invented certain new and useful Improvements in Ordnance Powder-Bags, of which the following is a specification. I

Thepresentinvention relates to those powder-bags which easily burn and are completely consumed in firing and aims to.render possible the regulation of the inflammability and combustibilityof these powder-bags.

According to this invention this objct is attained by producing the fabric from which the powder-bag is made from threads'of smokeless powder and from ordinary textilethreads,

(not nitrated.) The threads of smokeless powder are produced in anydesiredmanneras, for example, from a collodium solutionwhile for the other character of threads the I purpose will be served by selecting si1k.. The

fabric can be so constructed by way of'example that the threads of smokeless powder shall constitute the warp of the fabric and the ordinary textile threads be usedfor the weft, or the reverse may be the case, or both the warp and weft or the warp alone or the weft alone may be made up of both the smokelesspowder "threads and the ordinary textile threads alternated or intermingled with each other. Obviously thiswmethod admits of any desired varying of the proportionsof. the two kinds, of threads, since it is practieable. to alternate one, two, or even more of one kind of thread with only'one of the other kind of thread or otherwise use said threads in the proportion and combustibility of the powder-bag can be attained by substituting for the simple tens tile thread such threads that have been saturated more or less with a solution of smoke 2. An ordnance powder-bag consisting of a fabric produced from threads of smokeless powder, and of textile threads provided with a solution of smokeless powder.

In testimony whereof I have hereunto set my handin the presence of two subscribing witnesses.

of one, two, or more of one kind to one of the .otherin the formation of the fabric. v
